When systems were moved around, were all damaged ships that crashed into a black hole or star moved with them?
For example, in the Maw there are a few damaged ships. When the system was reworked, were all of the ships cleared out and the only wrecks there now hit Black Holes since the move?
Or could there be damaged ships nowhere near a Black Hole because they were at that system position before the Holes were added/moved around?

Typically, ships remained in the system they were in, unless they were in orbit then they moved with that planet. Since blackholes and suns shift the ships out of orbit, they wouldn't of moved if the sun/blackhole was moved to another system.

Per the Maw, all ships/stations (I believe) were moved out as more blackholes were added. They weren't moved in again, unless the owners moved them back in.
